ANKARA (Reuters) – A transparent and credible investigation into the killing of Saudi journalist Jamal Khashoggi has not yet been completed, Federica Mogherini, the European Union’s foreign affairs chief, said on Thursday, after talks with Turkey’s foreign minister.

Khashoggi, a critic of the kingdom’s de facto ruler Crown Prince Mohammed bin Salman, was killed in the Saudi consulate in Istanbul on Oct. 2. Riyadh has said it was seeking the death penalty for five suspects in the case.

Speaking at a joint news conference with EU Commissioner Johannes Hahn and Turkish Foreign Minister Mevlut Cavusoglu in Ankara, Mogherini said she was completely against any application of the death penalty.
